Risk factors
By Mayo Clinic staffUmbilical hernias are most common in infants — especially premature babies and those with low birth weights. Black infants appear to have a slightly increased risk of umbilical hernias. The condition affects boys and girls equally.
For adults, being overweight or having multiple pregnancies may increase the risk of developing an umbilical hernia.
